EXECUTIVE SUMMARY

In 2018, the Electricity Supply Industry continued to register growth, as

measured by the various Key Parameters highlighted below.

I. Peak Demand

The Peak System Demand (including exports to Kenya and Tanzania)

during the year 2018 was registered at 644.79 MW (in August 2018),

signifying a 3% increment, compared to the 625.27 MW registered as

the highest in 2017 (November 2017). This growth was mainly attributed

to growth in Domestic Demand.

II. Installed Generation capacity

The total Installed Capacity was 984 MW, having increased from 932

MW as at the end of December 2017. About 7.5 MW of the Installed

Capacity was accounted for by Off-Grids that generated and sold

their own electricity.

The Power Plants that attained their Commercial Operation Date in

2018 included five (5) Small Hydropower Plants and one (1) Solar

PhotoVoltaic (PV) Plant. These are:

(a) Nyamwamba HPP (9.2 MW);

(b) Lubilia HPP (5.4 MW);

(c) Nkusi HPP (9.6 MW)

(d) Mahoma HPP (2.7 MW;

(e) Waki HPP (4.8 MW); and,

(f) Kabulasoke Solar Power Plant (20 MW).

III. Electricity Supply to the National Grid

Twenty-four (24) Power Plants supplied electricity to the National Grid in

2018. These included three (3) Large Hydropower Plants, 14 Small

Hydropower Plants, three (3) Bagasse Power Plants, two (2) Thermal

Power Plants and three (3) Solar PhotoVoltaic Plants.

Overall, the Power Plants generated 4084.5 GWh in 2018, signifying a

6% increment compared to the 3,856.2 GWh generated during 2017. By

viii | P a g e


technology, 3638.1 GWh (89%) was from Hydro (Large Hydro and Small

Hydropower Plants) with the other technologies contributing 446.4 GWh

(11%).

IV. Transmission

UETCL purchased 4,078.5 GWh compared to 3,867.1 GWh purchased in

2017, signifying a 5% increment.

By source, about 3,157.5 GWh (77%) of UETCL’s energy purchases were

from the Large Hydropower Plants; 444.4 GWh (11%) from the Mini-

Hydropower Plants; 206.5 GWh (5%) from Bagasse Co-generation; 198.9

GWh (5%) from Thermal Plants; 32.3 GWh (1%) from Solar PV and 39.0

GWh (1%) imported from the neighbouring countries of Rwanda and

Kenya.

UETCL sells its power to both local distribution utilities and neighbouring

countries (Tanzania, Rwanda and Democratic Republic of Congo).

UETCL sold 3,925.4 GWh in 2018 compared to 3,715.9 GWh sold in 2017,

signifying a 6% increment.

UETCL made most of the energy sales (92%) to Umeme Limited, while

the sales to other distribution utilities and exports constituted about 2%

and 6% respectively. Transmission losses in 2018 were 3.8%.

The total Transmission Network Length as at the end of 2018 was 2,569.8

Kms (220KV = 1,008 Kms; 132KV = 1,526 Kms, 66KV = 35.2 Kms). The

Transmission Line Length increased by 942.9 Kms (58%) compared to

1,626.9 Kms as at the end of 2017 (220KV = 150 Kms; 132KV = 1,441.7

Kms, 66KV = 35.2 Kms) following the construction of the Buseruka

Substation and the Nkenda – Fort Portal - Hoima 220 KV Power Line.

V. Electricity Distribution

The utilities that wheel power over the National Grid purchased 3,685.2

GWh from UETCL during 2018, compared to 3,390.5 GWh in 2017,

signifying a 9% increment. UMEME purchased about 3,601 GWh (98%)

ix | P a g e


of the energy sold by UETCL, while the other Distribution Utilities

purchased 84 GWh (2%).

The energy purchased by Umeme Limited increased by about 8%, from

3,335.7 GWh in 2017 to 3,601.1 GWh in 2018, while the purchases by the

Mini-Grids increased from 54.7 GWh in 2017 to 84.1 GWh in 2018.

The energy sales of the Distribution Utilities increased by 9% in 2018

(3,065.2 GWh), compared to 2017 (2,802.5 GWh). The growth in energy

sales by the Distribution Utilities was majorly attributed to increment in

demand, especially from the Industrial Customers during 2018.

Across all Utilities, about 66% of the Energy Sales were made to

Industrial Customers (Medium Industrial = 16%, Large Industrial = 26%,

Extra Large Industrial = 24%) with sales to Domestic and Commercial

Customers constituting about 22% and 13%, respectively.

The Distribution Utilities recorded a Distribution Loss of 16.8% for 2018,

signifying a 0.5% improvement from 17.3% recorded in 2017. Umeme

Limited, the largest Distribution Utility reduced its Distribution Losses to

16.4% in 2018, from 17.2% in 2017; although this was below the target of

14.7% set by the Authority for 2018.

As at the end of 2018, there were 1,352,735 Customers on the National

Grid, signifying an increment of 15%, from the 1,177,812 Customers as at

the end of 2017. About 93% of the Customers on the Network were

served by Umeme Limited and 7% by Mini Grids.

VI. Off-Grid Generation and Supply

Off-Grid Power Plants are not connected to the National Grid, thus they

do not sell energy to UETCL. They generate and sell their energy directly

to Customers.

x | P a g e


WENRECO, the leading Off-Grid, generated and sold about 16.5 GWh

to end users in 2018, whereas Kalangala Infrastructure Services Limited

generated and sold about 1.4 GWh.

The main Off-Grids (WENRECO and KIS) had 19,431 Customers

(Domestic = 12,697; Commercial = 6,958 and Industrial = 13). The

distribution of Energy Sales by Customer Category shows that 56% of

the energy sold by the Off-Grids was to Commercial Customers, 25% to

Domestic Customers and 18% to Industrial Customers.

The Large Hydropower Plants generated 3,184.5 GWh in 2018,

constituting about 78% of the total energy dispatched during the year.

The energy dispatch from the Large Hydropower Plants in 2018 did not

significantly differ from the 3,173.0 GWh dispatched in 2017 (see

Appendix 1). BEL and Eskom (U) Limited recorded an average Plant

Factor of 75% and 46% respectively in 2018.

Figure 4: Energy dispatched by Large Hydropower Plants in GWh (2014-2018)

2.3.2 Generation from Small Hydro Power Plants

Fourteen Small Hydropower Plants generated and dispatched

electricity to the National Grid in 2018 (see Appendix 1), generating

454.5 GWh during the reporting period. Energy generated from the

Small Hydropower Plants increased by 69% in 2018 compared to 268.4

GWh generated in 2017.

The growth in generation in 2018 compared to 2017 is partly attributed

to the new plants that achieved commercial dates of operation. The

Plants are: Nyamwamba, Lubilia, Nkusi, Waki and Mahoma.

3.0 ELECTRICITY TRANSMISSION SEGMENT

3.1 Introduction

The Uganda Electricity Transmission Company Limited (UETCL) has

licenses for undertaking Systems Operations activities on High Voltage

Transmission Line, Bulk Power Supply and the Export and Import of

electricity to or from other countries. UETCL’s energy purchases are

driven by demand. This section presents the Peak Demand and UETCL

energy purchases and sales during the reporting period.

3.2 The Electricity Demand and Supply Nexus

A review of the system summaries captured by UETCL, shows a 3%

increase in Peak Demand in 2018 compared to 2017. The highest peak

system (including exports to Kenya and Tanzania) during 2018 was

registered as 644.79 MW (in August 2018) compared to 625.27 MW

registered as the highest in 2017 (November 2017). This growth was

mainly attributed to growth in Domestic Demand.

Figure 10 shows the Peak System Demand and Peak Domestic Demand

for the respective months in the period January 2017 to October 2018.

13 | P a g e


Figure 10: Monthly System Peak Demand January 2017 to October 2018

The comparisons between electricity Peak Demand and the total

generation Installed Capacity (Figure 11) shows that the Peak Demand

of 2018 was below the available capacity by about 40%.

3.3 UETCL Energy Purchases

Figure 12 shows UETCL energy purchases. During 2018, UETCL

purchased 4,078.5 GWh compared to 3,867.1 GWh purchased in 2017,

signifying a 5% increment.

By source, Figure 12 shows that 3,157.5 GWh (77%) of UETCL’s energy

purchases in 2018 were from the Large Hydropower Plants; 444.4 GWh

(11%) from the Mini-Hydropower Plants; 206.5 GWh (5%) from Bagasse;

198.9 GWh (5%) from Thermal; 32.3 GWh (1%) from Solar PV and 39.0

GWh (1%) imported from the neighboring countries of Rwanda and

Kenya.

Figure 12: Distribution of Energy purchased by UETCL (GWh) by Technology Source

Comparisons of energy purchases of UETCL by source in 2018 (see

Figure 13) compared to 2017 show an increment in energy from Small

Hydropower Plants (68%), Bagasse (38%), solar (27%) and imports

(191%). The high percentage increase in imports in 2018 (39.0GWh)

compared to 2017 was mainly due to a drop observed in imports in

2017 (13.4 GWh) compared to the previous years.

15 | P a g e


There was a drop in energy purchases from the Large Hydro and

Thermal Power Plants which is greatly attributed to the increase in

energy purchases from cheaper Renewable Sources including Solar

and Small Hydropower Plants.

3.4 UETCL Energy Sales

UETCL sells power to both local Distribution Utilities and to neighboring

countries (Tanzania, Rwanda and DRC Congo) as presented in Figure

14. UETCL sold 3,925.4 GWh in 2018 compared to 3,715.9 GWh sold in

2017, signifying a 6% increment.

time, should the Load Profile change. At present, there are three time

periods: Peak (the five hours between 18:00 and 23:00), Shoulder (the

thirteen hours between 05:00 and 18:00) and Off-Peak (the six hours

between 23:00 and 05:00).

Figure 16 shows that over the years, about half of the UETCL energy

sales are made during the shoulder time band, with the sales during

peak and off peak averaging 28% and 21% respectively.

Figure 16: Distribution of UETCL Energy Sales by ToU over the years

3.5 Transmission Energy Losses

Energy losses are computed as the difference between the energy

purchased and energy sold. UETCL’s transmission losses are presented

in Figure 17. During 2018, UETCL lost about 3.8% of the energy

purchased. Transmission losses have stagnated at averaged 3.9% over

the last three years (Figure 17).

4.0 ELECTRICITY DISTRIBUTION ON THE NATIONAL GRID

4.1 Introduction

This section presents the performance of the Electricity Distribution

Segment across the National Grid (not including Off-Grids that

generate and sell their own power). The Licensees on the National Grid

purchase electricity from the UETCL, the sole operator of the National

Transmission Grid.

Electricity Distribution on the National Grid is done by Six (6) Utilities,

namely: UMEME Limited, Uganda Electricity Distribution Company

Limited, Pader-Abim Community Multipurpose Electricity Cooperative

Society Limited, Kilembe Investments Limited, Kyegegwa Rural

Electricity Cooperative Society, and BECS. UMEME Limited is the largest

operator on the National Grid followed by UEDCL.

UEDCL operations are spread in eight Service Territories that include;

Central North Service Territory (CNST), Eastern Service Territory (EST),

Mid-West Service Territory (MWST), North East Service Territory (NEST),

North-North West Service Territory (NNWST), Southern Service Territory

(SST), Southern West Service Territory (SWST), North Western Service

Territory (NWST). In this Report, other than UMEME Limited, the other

Distribution Utilities are defined as Mini-Grids.

4.2 Energy Purchases and Sales by Distribution Utilities

The energy purchases and sales of the Distribution Utilities are

presented in Table 3. Overall, the Utilities that wheel power over the

National Grid purchased 3,685.2 GWh during 2018 compared to 3,390.5

GWh in 2017, signifying a 9% increment. The energy purchased by

UMEME Limited increased by about 8% from 3,335.7 GWh in 2017 to

3,601.1GWh in 2018 while the purchases of the Mini-Grids increased

from 54.7GWh in 2017 to 83.2 GWh in 2018.

Mini-grids 21.5 36.4 25.2 40.0 56.1

Distribution Utilities are licensed to sell power to End-users. Table 3 shows

that the energy sales of the Distribution Utilities increased by 9% in 2018

(3,065.2 GWh) compared to 2017 (2,802.5 GWh). The growth in energy

sales by the Distribution Utilities is majorly attributed to an increment in

Demand especially from the Industrial Customers during the reporting

period.

4.2.1 Energy Sales by Customer Categories

Electricity customers in Uganda are classified as Domestic,

Commercial, Medium-Industrial, Large-Industrial, Extra-Large Industrial

and Street Lighting by the Electricity Regulatory Authority.

The energy sales by Customer Tariff Category during 2018 is shown in

Figure 20. Across all Utilities, about 66% of the energy sales were made

to Industrial Customers (Medium=16%, Large=26%, Extra-Large=24%)

with the sales to Domestic and Commercial Customers constituting

about 22% and 13%, respectively.

22 | P a g e


Figure 20: Energy sales of Distribution Utilities by Customer Categories

4.3 Energy Distribution Losses

Electricity Distribution Losses still remain one of the major challenges

faced by Uganda’s Electricity Supply Industry. The Distribution Losses

presented here include both Commercial and Technical Losses and

computed as the difference between energy purchased and energy

sold.

Figure 21 shows the five-year historical trend of Distribution Losses.

Overall, the Distribution Utilities recorded a Distribution Loss of 16.8%

during 2018, indicating a 0.5%-point improvement from 17.3% recorded

in 2017. UMEME, the main operator reduced the Distribution Losses to

16.4% in 2018 from 17.3% in 2017; although this was below the target of

14.7% set by the Authority for 2018.

23 | P a g e


Figure 21: Distribution Losses (%)

4.3.1 Energy Losses for UMEME Limited

UMEME Limited is Uganda’s main Distribution Utility, selling about 98% of

the energy that was sold to the end-users in 2018 (see Table 3). Figure

28 shows a reduction in percentages of energy losses of UMEME over

the years with energy losses reducing from 17.2% in 2017 to 16.4% in

2018. Whereas UMEME Limited recorded a reduction in the energy

losses, the performance was below the set targets of the Authority.

24 | P a g e


Figure 22: UMEME Limited’s Distribution Energy losses

4.3.2 Energy Losses for Mini-Grids

The overall loss factor for the Mini-Grids increased from 27% in 2017 to

33.4% in 2018, off the Authority set target of 20.68% for the period. By

service territory operated by the Mini-Grids, Figure 23 shows that the

highest energy losses (48.7%) in 2018 were recorded in the North

Western Service Territory (NWST) of UEDCL.

Overall, UEDCL, the second largest Distribution Utility, recorded an

overall Distribution Loss of 36.7%. The energy losses for the other Mini-

Grids including PACMECS, KIL, BECS, and KRECS during 2018 were 9.8%,

16.7%, 23% and 24.8%. Various factors accounted for the losses

including lack of evacuation lines.

25 | P a g e


Figure 23: Distribution Energy Losses in 2018 by Service Territory

4.4 Customer Growth

At the end of 2018, there were 1,352,735 Customers on the National

Grid (see Figure 24), signifying a 174,923 (15%) increment from the

1,177,812 Customers at the end of 2017.

About 93% of the Customers on the Network are served by UMEME

Limited, with the Customers under the jurisdiction of Mini-Grids

constituting 7%. The Electricity Supply Industry has seen the Customer

connections almost double over the five-year period between 2014

and 2018.

Figure 24: Total Customers on the Network as at the end of December 2018

By Customer Tariff Structure, Table 4 shows that majority (92%) of the

Customers on the Network are classified as Domestic Customers, with

the other Customer Categories including Commercial, Industrial and

Street Lighting combined constituting about 8%.

4.5 Distribution Network Length

At the end of December 2018, the length of the Distribution Network

was 45,423.1 kilometers (Kms) translating into an increment of 5,144.1

Kms compared to the 40,279.0 Kms at the end of 2017. UMEME Limited

Network increased by about 512 Kms, while the distance by other Mini-

Grids combined increased by about 4,631.7 Kms.

The increment in the Network Length of Mini-Grids was mainly

attributed to the Grid Extensions by the Rural Electrification Agency

(REA), the Government Agency that operationalizes Government's

Rural Electrification Function.

27 | P a g e

4.6 Staff in the Distribution Segment

The movements in the number of contract3 employees in the Electricity

Distribution Segment over the years is presented in Figure 26. At the end

of December 2018, there were 1,907 employees in the utilities

distributing electricity via the National Grid of whom 1,504 (79%) were

employed by UMEME Limited. The number of staff in the Distribution

Segment at the end of December 2018 increased by 4%, compared to

the 1,828 staff at the end of 2017.

Figure 26: Employees in the Electricity Distribution Segment

4.7 Transformation Capacity

Figure 27 shows the Transformation Capacity on the Distribution

Network. At the end of 2018, there were 14,815 Transformers on the

Distribution Network (UMEME Limited=12,476; Mini-Grids=2,331) with a

total Transformation Capacity of about 2,004MVA (UMEME=1,842 MVA;

Mini-Grids=162MVA). The total Transformation Capacity in 2018

increased by 6% compared to the 1,855 MVA reported in 2017

(UMEME=1,744 MVA; Mini-Grids=141 MVA). Majority (37%) of the

Transformers of the Distribution Network are of 50KVA capacity followed

by the 100 KVA (20%) and 200 KVA (14%). 3 This does not include the casual employees

28 | P a g e


Whereas there was an increment in Transformation Capacity in 2018

compared to 2017, these were below the Transformation Capacity

reported in 2016, which was attributed to exclusion of the privately

owned Transformers.

5.0 ELECTRICITY GENERATION AND DISTRIBUTION BY OFF-GRIDS

5.1 Introduction

Off-Grid Power Plants are not connected to the National Grid, thus they

do not sell energy to Uganda Electricity Transmission Company Limited.

They generate and sell their energy directly to the Customers.

Nyagak 1 Hydropower Plant operated by West Nile Rural Electrification

Company Limited (WENRECO) and Kalangala Infrastructure Services

(KIS) operated by Kalangala Infrastructure Services Limited are the

largest Off-Grid Power Plants with Installation Capacities of 3.5 MW and

1.6 MW.

There are smaller Off-Grid Plants operated by Kisiizi Hospital Company

Limited, Absolute Energy Limited, Bwindi Community Micro Hydropower

Limited and Pamoja Energy Limited, among other companies. The

performance of these Plants during 2018 is not reported on, as they are

Licence-Exempted companies, with less stringent reporting

requirements.

5.2 Energy Generation and Sales by the Major Off-Grids

The energy generation and sales of the leading Off-Grids during 2018

are presented in Figure 28. WENRECO, the leading Off-Grid generated

and sold about 16.5GWh to the End-Users in 2018, whereas Kalangala

Infrastructure Services Limited generated and sold about 1.4GWh to

the End-Users.

33 | P a g e


Figure 28: Energy sold by Off-Grids from January to September 2018 (in GWh)

As at the end of 2018, the main Off-Grids had 19,431 Customers

(Domestic=12,697; Commercial=6,958 and Industrial=13). The

distribution of Energy Sales by Customer Category (see Figure 29) shows

that 56% of the energy sold by Off-Grids was to Commercial Customers,

25% to Domestic Customers, and 18% to Industrial Customers.

5.3 Staff, Customers and Distribution Network in Off-Grids

At the end of 2018, WENRECO and KIS had 112 employees

(WENRECO=97, KIS=15) a number that has remained relatively constant

over the previous two years.

Considering the Length of the Network, the major Off-Grids operated a

total of 851.1 Kms and this constitutes 0.5 Kms, 244.3 Kms and 606.3 Kms

of Street Lights, 11KV and 33KV, respectively.

6.0 TREND OF ESI-RELATED MACRO-ECONOMIC VARIABLES

6.1 Introduction

The Electricity Supply Industry in Uganda is greatly influenced by the

Macro-Economic changes. These include the Consumer Price Index

(CPI), the US Dollar Producer Price Index (US PPI), Exchange Rate of the

Shilling (Shs) to Foreign Currencies and International Fuel Prices. Every

year, ERA sets Base Tariffs which are then adjusted on a Quarterly Basis

for these macro-economic factors. This section provides the

movements in the Macro-Economic Factors.

6.2 Crude Oil Prices

Uganda has two Thermal Power Plants; - Jacobsen and Electromaxx.

These Power Plants use Heavy Fuel Oil (HFO) for power generation. As

Uganda currently imports all the oil used, changes in oil prices on the

International Market affect the generation costs of these Thermal

Power Plants thereby impacting on UETCL’s costs of purchasing power.

Movements in the prices of crude oil on the International Market over

the reporting period are presented in Figure 30. Whereas there was a

drop in the oil prices in November 2018 compared to the previous

month, the oil prices per barrel (US$/b) increased significantly from

January 2017 to October 2018.

The increase in oil prices has been attributed to indications by key

OPEC members; Russia and Saudi Arabia aimed at supporting the

production adjustment to rebalance the Oil Market.

6.3 Inflation

Inflation is measured by two parameters, the CPI and the US PPI. The

CPI is used to adjust for costs denominated in local currency, while the

US Producer Price Index (PPI) is for adjustment of costs denominated in

the US Dollar currency (US$).

Changes in price indices (CPI or US PPI) in a given period denote the

level of inflation in that period. The Tariff Adjustments are based on core

inflation, for better reliability of inflation trends.

6.4 Consumer Price Index (CPI)

Consumer Price Index (CPI) measures changes in the price level of the

market basket of consumer goods and services purchased by

households. The Tariff Methodology uses core CPI, which by definition

excludes energy and food prices because of their volatile nature. The

CPI used in the Tariff Methodology and presented in this Report (Figure

31) is as published by the Uganda Bureau of Statistics (UBOS).

The annual Consumer Price Index for the month ending November

2018 was 169.77 compared to 164.15 in November 2017. The annual

37 | P a g e


underlying inflation rate reduced from 3.9% in November 2017 to 3.42%

in November 2018.

This reduction is largely attributed to improved Agricultural production,

leading to low food inflation during the second half of the year and

contained Foreign Exchange Rate pressure amidst a tight Monetary

Policy Regime exercised by Bank of Uganda in 2018.

Figure 31: Monthly Consumer Price Index (CPI)

6.5 United States Producer Price Index (US PPI)

This measures the average change over time in the selling prices

received by producers for their output. The US PPI is published by the

Bureau of Labor Statistics.

The US PPI increased from 200.5 in November 2017 to 205.4 in

November 2018, representing a 2.34% increment. This was mainly

attributed to finished consumer goods and crude material.

6.6 Exchange Rate

Up to 70% of the costs in Uganda’s ESI are denominated in Foreign

Currency. Uganda’s ESI Tariff Methodology provides for Quarterly

Adjustment of a portion of Electricity Industry costs denominated in

Foreign Currency for changes in the Exchange Rate of the Uganda

Shilling against the US Dollar (US$). The Methodology uses the Mid-

Exchange Rate (the average of the buying and selling rates) for the last

day of the month as published by Bank of Uganda (BoU).

The last day of the Month’s Mid-Exchange Rate of the Uganda Shilling

(Shs) against the US Dollar (US$) for the Quarterly Tariff Determination

periods between November 2016 and November 2018 is presented in

Figure 2.

The Exchange Rate at the end of November 2018 was Shs 3,728.21/US$

compared to Shs 3,634.92/US$ at the end of November 2017. This

39 | P a g e


movement represents a 2.57% depreciation of the Shilling against the

US Dollar at the end of November 2018.

The Uganda Shilling was a little unstable throughout 2018 peaking

3,850/US$ during the Second Quarter of 2018, subsiding slightly into the

Third and Fourth Quarters of 2018, owing to improved Foreign Currency

inflows and relaxed Central Bank Monetary Policy and investments in

Treasury Bills, Government Bonds and Infrastructure Investment

requirements together with continued Government Policy for

promotion of local content through the “Buy Uganda Build Uganda”

Policy.

7.0 RETAIL TARIFFS

The Authority sets Tariff Rates for the Distribution Licensees in

accordance with Sections 10 and 75 of the Electricity Act, 1999.

7.1 Grid Retail Tariff

FFigure 34 shows the Grid Tariffs for UMEME Limited and UEDCL by

Customer Category over the Tariff Review Periods in 2017 and 2018.

UMEME Limited and UEDCL operate under the same Tariff Structure as

their services are extended across the same service areas.

The observed fall in the Tariff for the Extra-Large Customer Category

during the Third and Fourth Quarters of 2018 compared to the other

Customer Categories or Tariff Review Periods (FFigure 34) is attributed to

the Bujagali Energy Limited Refinancing which was completed on 19th

July 2018.

During the consultative process, it was agreed that the benefits arising

out of the refinancing of the Bujagali Hydropower Plant are allocated

to the Extra-Large Industrial Consumers through the Fourth Quarter of

2018 and this status quo was maintained for the Extra-Large Industrial

Consumers in the First Quarter of 2019.

customers served by the Mini-Grids (other than UEDCL) over the Tariff

Review Periods in 2018 in comparison with 2017. Comparisons of Tariffs

of the Quarter ending the years 2017 and 2018 show the highest Tariff

increments among the customers served by PACMECS (4-6%) which

was attributable to increase in operational costs.
